Beast concludes on a bittersweet note, as Nate Samuels defeats the rogue lion stalking his family but is severely injured himself. After the lion kills poacher Martin and mortally wounds Nate’s daughter Meredith, Nate ignites leaking gasoline to immolate the lion as it mauls him. The ending implies Nate conquered the beast, but at great personal cost. Though Nate, his father, and his daughters survive, they are emotionally scarred and Meredith faces a difficult recovery. The finale suggests the true “beast” was the darkness of grief and trauma Nate carried from his wife’s death. By defeating the lion, Nate symbolically overcame this inner beast plaguing his psyche and endangering his family. However, his wounds represent lingering emotional damage. The coda reveals Nate writing a book about his experience, implying sharing his story is part of the healing process. Though life will never be the same again, Nate’s courage and sacrifice for his family signify hope can emerge even from tragedy. Beast’s conclusion conveys that the wildness lurking inside us and in nature can be harnessed for good through protective love. By channeling his primal fierceness into saving his family, Nate embraces his role as patriarch and redeems his perceived failure to safeguard his wife.
